[0013]

Next, the present invention will be described with reference to embodiments. FIG. 1 shows an example of the configuration of the IC card of the present invention. 1 is an IC module, 2 is an EEPROM (el
ectrically erasable programmable read only memory
), 3 is RAM (random access memory), 4 is RO
M (read only memory), 5 is CPU (central process)
sing unit), 6 is an interface unit, 7 is an application program, 8 is condition determination means, 9 is update means,
10 is a condition value, and 11 is a set value. The IC card generally has a structure in which the IC module 1 is embedded in a base material portion in which plastic sheets such as vinyl chloride are laminated in multiple layers. The IC module 1 performs data storage and processing.
It is an assembly in which electrical components such as a C (integrated circuit) chip, an interface unit 6 for performing contact or non-contact data communication, and the like are integrated. In the completed base part,
By embedding the IC module 1 whose characteristics have been checked, the non-defective product rate of the IC card is increased, and quality and reliability can be obtained.

The IC module 1 is composed of hardware such as a one-chip microcomputer and software such as an operating system (OS) and an application program for operating the same. That is, the IC module 1 is a very small computer system.

The condition judging means 8 judges whether a predetermined condition is satisfied or not. The updating means 9 updates the data and / or the contents of the data processing when the condition judging means 8 judges that the condition is satisfied. The condition determining means 8 and the updating means 9 are realized as one function of an application program of the IC card (or the IC module 1).
As shown in FIG. 1, an application program is stored in the EEPROM 2 in the present invention. In the present invention, since the process of updating the condition value 10 and the set value 11 is performed, the electrically rewritable EEPROM 2 is suitable as a storage device.

The condition value 10 is, for example,
The number of uses, etc. The setting value 11 is, for example,
Point rate, premium rate, usage limit, ability data,
And so on. If the accumulated usage amount is the condition value 10,
When the condition determining unit 8 determines that the accumulated usage amount matches the predetermined accumulated usage amount, the updating unit 9 updates the condition. When the number of uses is set to the condition value 10, when the condition determining unit 8 determines that the number of uses matches the predetermined number of uses, the update is performed by the updating unit 9.

In the case where the point rate is set at 11, the point rate is updated by the updating means 9 when the condition determining means 8 determines that the predetermined condition is satisfied. When the premium rate is set to 11, the updating unit 9 updates the premium rate when the condition determination unit 8 determines that the predetermined condition is satisfied. In addition, when the usage limit is set to the set value 11,
When the condition determining means 8 determines that the predetermined condition is satisfied, the updating means 9 updates the usage limit.
Further, when the capability data is set to the set value 11, when the condition determination unit 8 determines that the predetermined condition is satisfied, the capability data is updated by the updating unit 9. Updating the performance data is suitable for an IC card for a game device.

The interface unit 6 is a part for performing communication control, electrical level conversion, and the like for performing data communication with an external device (for example, a reader / writer). Contact type I
If it is a C card, it is connected to an external device at an electrode terminal. If it is a non-contact type IC card, it is electrically connected to an external device by a coil or a loop antenna.

The operation of the IC card of the present invention having the above configuration will be described. In the present invention, the purpose of use of the IC card is not particularly limited, but a point service will be described as an example for easy understanding. By adding an application corresponding to the point service to a main application of the IC card, the point service is realized in the IC card. In that case, the operating system of the IC card (OS: oper)
ating system), specifically, “MULTO
A multi-application compatible operating system such as "S" or "Java" is preferable.
"TOS" is an M operated by MXI (Mondex International), MasterCard International, etc.
A general-purpose OS for multi-application IC cards promoted by the ASCO Consortium. "Java" is an OS of Sun Microsystems, Inc. There is "Java Card" as a subset for IC cards.

Usually, the IC card is carried by its owner. When the owner purchases an article at the store, the owner hands the IC card to the store clerk. The clerk receives the IC card and reads the IC card reader.
Attach the IC card to the writer. The reader / writer and the register are terminal devices of the sales system of the store. The information included in the IC card and the information generated by the register when the owner purchases the article in the store are centrally managed by the sales system of the store.
Therefore, every time you purchase an article using an IC card,
In the IC card, at least the condition value 10 (cumulative use amount, use number) is updated.

FIG. 1 shows an example of the sales system.
Although a C card configuration can be provided (conventional system), in the present invention, the IC card itself has that configuration. By doing so, it is possible to provide a fine-grained service to one customer while reducing the processing load on the sales system. The condition determination means 8 of the IC card monitors the condition value 10. This monitoring may be performed at all times, but does not make much sense. The processing is started when the IC card is attached to the reader / writer or when the condition value 10 (cumulative use amount, etc.) is updated (START). Then, when the IC card is removed from the reader / writer or when the set value 11 (point rate, etc.) is updated, the processing is terminated (END).

FIG. 2 is a flowchart showing the processing steps in the IC card of the present invention. First, in step S1 of FIG. 2, the condition determining means 8 determines whether or not a predetermined condition (accumulated usage amount, etc.) is satisfied or not.
In the case of non-conformity, it is in a standby state until it becomes compatible. In the case of a match, the process proceeds to step S2. In step S2, the updating unit 9 updates the set value 11 (point rate, etc.). Next, in step S3, it is determined whether to end or continue this processing with reference to the IC card status (for example, whether or not the card is attached). . On the other hand, if the processing is to be terminated, the processing is terminated.

For example, if the point rate is 10%, if the accumulated usage amount exceeds 100,000 yen, 1
The percentage is added and the point rate is automatically updated to 11%. With this update, 11% can be applied as the point rate to the purchase amount exceeding 100,000 yen in the next purchase or including this purchase.

[0024]

As described above, according to the IC card according to the first aspect of the present invention, there is provided an IC card capable of performing a detailed service for each customer without restriction on update conditions and update contents. . IC according to claim 2 of the present invention
According to the card, the main application part of the IC card can be easily realized without any modification. According to the IC card according to the third aspect of the present invention, the update is performed when the accumulated usage amount matches the predetermined accumulated usage amount. According to the IC card according to the fourth aspect of the present invention, the update is performed when the number of uses matches the predetermined number of uses. According to the IC card according to claim 5 of the present invention,
When a predetermined condition is satisfied, the point rate is updated. According to the IC card according to the sixth aspect of the present invention, the premium rate is updated when a predetermined condition is satisfied.
